STUDY ON IMPACT OF AQUA DRUGS AND CHEMICALS ON SHRIMP HEALTH IN BANGLADESH (Pages : 17 - 23)

An investigation was carried out to know the impact of aqua-drugs and chemicals on shrimp health in the coastal belt of Bangladesh. Eight different categories of aqua-drugs and chemicals were found to use in shrimp farming activities. They were oxygen suppliers, disinfectants, growth promoters, antibiotics, pond preparator, gas removal, insect killers and microbe killers. In medicine shops of investigated areas, 39 different types of aqua-drugs and chemicals were recorded. Some shrimp of Cox’s Bazar region were yellowish, brownish or darker than normal appearance. Clinically health condition of shrimp of Khulna region was better than those of Cox’s Bazar region. Histopathologically, muscle of control shrimp (without drugs treated) of all the investigated areas of Cox’s Bazar and Khulna regions were almost normal except some vacuums in control shrimp muscle of Fakirhat. In case of midgut of control shrimp there were some vacuums, necrosis and pyknotic cells in Fakirhat and Khulna. In the drugs treated shrimp of all the investigated areas of Cox’s Bazar and Khulna regions, there were remarkable pathological changes like necrosis, vacuums and pyknosis in muscle and midgut of shrimp.Download
